Ruud was issued his patent for the coiled tube Automatic Water Heater on September 6, 1898. [17] A 1915 diagram showing the innards of a Ruud instantaneous water heater. Ruud's business expanded as he popularized and improved on his instant water heater design. In 1908, Ruud Manufacturing acquired two local heating and plumbing firms.
An air purifier or air cleaner is a device which removes contaminants from the air in a room to improve indoor air quality. These devices are commonly marketed as being beneficial to allergy sufferers and asthmatics , and at reducing or eliminating second-hand tobacco smoke .
Crosthwait's expertise was on air ventilation, central air conditioning, and heat transfer systems. With this knowledge he created many different heating systems, refrigeration methods, temperature regulating devices, and vacuum pumps. For these inventions he holds 39 United States patents, as well as 80 international patents. [1]
A water heater is still sometimes called a geyser in the UK and South Africa. Maughn's invention influenced the work of a Norwegian mechanical engineer named Edwin Ruud. The first automatic, storage tank-type gas water heater was invented around 1889 by Ruud after he immigrated to Pittsburgh, Pennsylvania (US). The Ruud Manufacturing Company ...
Plate precipitators are commonly marketed to the public as air purifier devices or as a permanent replacement for furnace filters, but all have the undesirable attribute of being somewhat messy to clean. A negative side-effect of electrostatic precipitation devices is the potential production of toxic ozone [13] and NO x. [14]
Equatic’s process combines electrolysis with direct air capture to provide two valuable products, creating a dual-revenue stream. Its clean hydrogen production will help subsidize the cost of carbon removal, quickly bringing it down to less than $100 per tonne before 2030. The OSAs will be manufactured at a San Diego electroplating facility.
Greathead invented and built his own design of a shield as the contractor for that project, under Peter W. Barlow who was the engineer. Since Beach was a patents lawyer, it is likely he discovered the 1869 Greathead patent and the patent application by Barlow from 1864, using an imitated Barlow's patent design for engineering the PTS tunnel design.
Slingshot is a water purification device created by inventor Dean Kamen. [1] Powered by a Stirling engine running on a combustible fuel source, it claims to be able to produce drinking water from almost any source [2] by means of vapor compression distillation, [3] requires no filters, and can operate using cow dung as fuel.
